Tools for Turning Mill Tools for Turning Mill  The turning mill is a machine that combines turning and milling functions. Now an interface (between workpiece and toolholder - equivalent to the arbor for milling) is available for the turning mill that fulfils the ICTM standard.  ICTM standard was developed by 16 companies in Japan, as the interface between turning mill machines. It is based on the two-face restraint type standard “ISO 12164-1:2001 HSK Standard Shank”  This standard became an International Standard as ISO Standard “ISO12164-3:2008” in 2008. Description is indicated as HSK-T¡¡. Features (1) Compatible with HSK-A type for Machining Center. Interface HSK Tool Post Main Spindle Toolholder for Turning (HSK-T type: ICTM standard) HSK spindle (Compatible) Turning Mill Machining Center Toolholder for Milling (HSK-A type) (2) Machining precision for turning has improved by minimizing the gap between the drive key slot on toolholder side and the drive key on toolpost side.
